Awesome, thanks!
-Yup, way to check dwarf stats is on the TODO list.
-A slider in player's hands would be a bit weird, but I am constantly improving performance and tuning the mountain reclaiming, so that it feels good and not like it takes too many ores too fast, so that beautiful gem piles can stil form, but at the same time keeping in mind performance impact, which is a hard thing to get right. However I will be adding higher value ores, so that instead of dropping 2-3 small ones, you drop 1 high-value one, especially in the late game, helping reduce overall count.
-Dens should protect mountains from normal hits, but a lot of hits like dynamite and laser deal damage to both at once.
-I probably won't add dwarf selling since there's not much reason for it (btw you won't be forced to buy 7 miners in full release), but I might have to increase max building height to 5. Though atm even with 4, you can build all current buildings + all future ones, with potentially only missing one slot, which could be a fine strategical decision, though I assume most players wouldn't be happy with that so I'll prob need more slots lol.
Thank you for feedback. Glad to hear your kind words! :)
